IMPROVEMENT IN SAPI-3S.

The Schedule referred to in these Letters Patent and making part o! the same To all whom it may concer-n.-

Be it known that I, WILLIAM MGFARLAND, ot' Williamsburg, in the county of Kings, and State of New York, have invented a new and useful Improvement inBurglar-lroof Safes; and Ido hereby-declare that the following is afull, clear, and exact descriptiont-hereof, which -will enable others skilled inthe art to make and use the same, reference being had to the accompanying drawings, forming partof this speciiicatiou.'

Figure l is a vertical section of my improved safe, taken through the line x x, fig. 2.

My invention has for its object to improve the construction Aoi' my improved safe, patented September 14,

A1869, and numbered 494,761, so asV to 'make it more convenient in construction and use, `while bein g equally strong and safe against the attacks of burglars; and It 4consists in the construction of the out-er and inner parts or shells, as hereinafter morefully described. The safe is made rectangular in its` general form, with the cross-corners rounded oli, as shown in tig. 1. Thewouter case or shell A is made of a single platel of metal, one and a quarter inches thick, bent into the proper form, and havingrits edgessecurely and thoroughly welded together.- g I The weld may be in the middle part of either of the plane orflat 'sides of the safe, preferably upon the bottom side, but never at or .near any of the rounded corners. By this construction of the shell A, there willbe no angle or corner for the burglar to operate upon, the said shell being'continuous, and without square corners. The steel ribs B are formedl upon the steel sides of a plate, C, of steel and iron, formed by the well-known process.

The steel-ribbed plate B C istheu bent into the proper form to lit into the interior of the rounded corners of the shell A.

The ribbed plate B C may be made in one piece, with the joint in the middle pal-toi' one ot' the plane sides, or it may be made in two pieces, with the joints in the middle parts of two opposite sides, or the side parts of saidhribbed plate may have the rounded cor ners formed in them, near their upper and lower edges, the plane spaces between said edges being ocn cupied by plane pieces of said ribbed plate, in every case, the rounded corners being formed in the-solid body of the plate.

By this construction, should the outer shell A b pierced, it will be impossible for the steel ribs B to be broken -by a blow, and removed in pieces, as the iron plate C, upon which said ribs are formed, serves as a backing, to preserve said ribs from being th ns broken and removed. Y

I The ribbed plate B C is secured to the outer shell A by steel-pointed bolts, passing through said ribbed plate, and entering the outershell A.

E are angular bands or plates, placed in the angles between the body and the ends ofthe safe, one ange ot' each sof said angular plates being bolted to the shell A, through the ribbed plate B C.

The rear` end of the safe is bolted to the other flange of the rear angular plate, with steel-pointed bolts passing through the said dange, through the ribbed plate B C, and into the outer shell A.'

The door ofthe safe shuts against the other .flange ot' the, forward angular plate E, the lock ot' said door projecting inward, and the bolts of said lock shooting along the inner surface of said flange. v

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- A'burglar-proof safe, composed of outer shell A, 'mner ribbed or serrated shell B C, and angular plates E, constructed, arranged, and iitted together in the manner described. l
